' 'BOTTL'E-STOPPER.

SPECIFICATION forming part of Letters Patent No. 603,364, dated May 3, 1898. Application filed December 18, 1897. Serial No. 662,501. (No model.)

To all whom it may concern.-

Be it known that I, PHILIP LINDEMEYR, a resident of Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Bottle-Stoppers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to makeanduse the same.

I The invention relates to-cap-stoppers for bottles, and has for its object to increase the economy and efficiency of such devices; and

it consists in'the construction hereinafter described and pointed out.

In the accompanying drawings, Figure 1 is a plan of the cap and bottle-neck. Fig. 2 is a partial vertical section of the same. Fig.

3 is a similar view showing an additional de-' 4; denotes a metal cap fitting the reduced portion of the bottle-neck and having fingers 5 crowded into the depression or seat 3 and held between its outer and inner walls, as indicated in the drawings. These fingers are indicated in Fig. l in considerable numbers; but the number of them is immaterial.

6 denotes a wax packing, and 7 a cover for the packing, consisting, preferably, of parchment-paper. Thispaoking and paper or any equivalent packing having been placed in the cap the latter is forced onto the end of the neck, and its fingers 5 are crowded or sprung into the depression in manner to be engaged by the walls thereof and hold the cap upon the bottle-neck.

In some cases a stripping-wire 8 (see Figs. 3 and 4) is placed in the groove 3'.

In Fig. 5 a modified stripping-wire 8 is shown provided with a seat for the foot of the cap-flange and adapted to hold the cap on the bottle. The bottom of the flange is sprung into the seat in substantially the same Another form of bottle-neck, including a seat or depression and adapted to receive the foot of the cap, is shown in Fig. 6, which form is considered preferable under most conditions. It avoids the undercut groove. Preferably the sides of the depression 3 will be approximately parallel and sufliciently deep and wide to receive the foot or bottom of the cap flange 5 when bent, substantially as shown in said figure. This .flange is slitted or notched to enable it to be more easily pressed-into its seat in the bottle-neck. The ends of the spring-fingers formed by this slitting or notching of the cap-flange will when they are sprung into their seat in the groove bear against the outer wall of the groove, and they can be then easily sprungout of the same by a stripping-wire or other means.

Having described my invention, I claim- 1. In combination a bottle provided with a groove having a vertical wall outside the circumference of the neck, a cap having a flange extended below the mouth and laterally embracing the bottle-neck on its exterior, said flange being provided with fingers sprung into the groove and having their outer ends bearing against the outer vertical wall of the same and their inner ends against the opposite wall of the groove, substantially as described.

2. In combination a bottle provided with a groove having a vertical wall outside the circumference of the neck, a cap having aflange extended below the mouth and laterally ernbracing the bottle-neck on its exterior, said flange being provided with fingers sprung into the groove and having their outer ends bearing against the outer vertical wall of the same and their inner ends against the opposite wall of the groove, and a packing covering the mouth of the bottle substantially as described.

3. In combination a bottle provided with a groove having a vertical wall outside the circumference of the neck, a cap having a flange extended below the mouth and laterally embracing the bottle-neck on its exterior, said flange being provided with fingers sprung into the groove and having their outer ends bearing against the outer vertical wall of the same and their inner ends against the opposite wall of the groove, said groove being formed in a wire secured to the bottle-neck, substantially as described.
